[PATCH 05/11] userns: Convert jffs2 to use kuid and kgid where appropriate

From: "Eric W. Biederman" <ebiederm@xmission.com>

- General routine uid/gid conversion work- When storing posix acls treat ACL_USER and ACL_GROUP separately so I can call from_kuid or from_kgid as appropriate.- When reading posix acls treat ACL_USER and ACL_GROUP separately so I can call make_kuid or make_kgid as appropriate.
